Question

870 g of brass contains 40 percent zinic and the rest is copper.find the mass of zinic and copper in the alloy​

Answer 1

Mass of zinc = 40/100*870 = 348

Mass of Copper = 60/100*870 = 522

Therefore, the mass of zinic in the alloy is 348 and the mass of copper in the alloy is 522.

Answer 2

Explanation:

Mass of Zinc = 870g * (40/100) = 348g.

Mass of Copper = 870g - 348g = 522g.
